If
realistic limits are imposed on the choices I would go with 1000 ft.
For the angle of elevation I would chose 34°. This because as we
know an angle of elevation is the angle between the observer's’
line of sight and a horizontal line when the observer looks upward.
If
you wanted to find the height of the cliff you would use the
following:
Tan34
= x/1000
x
= tan(34)*1000
x
= 674.51 ft.
I
hope this helps, Regards.
